The Lowdown
Alright, this is Rusty comin' at ya from the beach. Let's have a look at what's on the cards for Jaconé over the next couple of weeks.
Well, it's a bit of a slow burner to start, but once it fires, it really fires. The first few days are a bit average, but from Sunday the 23rd of August, we start to see some real potential buildin'. The standout period is definitely the middle of the week, with some serious size and energy rollin' in.
The first real highlight is Sunday morning, the 23rd of August. We've got a solid 6ft swell from the SSW, a period of 10 seconds, and the wind is a clean cross-off from the ENE at 9 mph. The water's a pleasant 73°, which is pretty normal for this time of year. For the experienced crew, the real gem is Monday morning, the 24th of August. The swell jumps to 8ft from the S, with a longer 13-second period, and combined wave energy is a hefty 1883. The wind is light and cross-off, making for excellent, clean conditions. This is a big day for the confident surfer.
Tuesday the 25th keeps the energy high, with an 8ft S swell and a 14-second period (2736 energy) in the morning, and clean cross-off winds. Then Wednesday the 26th of August—this is the one to circle. The morning session is looking like the best of the entire forecast. We've got an 8ft swell from the S, a very long 16-second period, and the combined energy is a massive 3543. That's a lot of power. The wind is a gentle 9 mph cross-off from the ENE. This is expert territory, but it's going to be pumping.
Thursday the 27th is still very good, with a 7ft S swell (1801 energy) and proper offshore winds from the ENE in the morning. The surf tapers off through Friday and Saturday, but Saturday arvo the 29th gets a mention. The swell is a smaller 6ft from the ENE, but the wind goes glassy, and the period is a short 8 seconds. It'll be clean and fun for the logs or a mid-length.
After that, we hit a dry spell. The 30th and 31st of August, and the first few days of September, are looking pretty flat or messy. There's a gap of several days with nothing really recommendable. There's a little flicker of hope on the 3rd of September, with a glassy morning and a small SSW swell, but it's not enough to write home about. The 6th of September is the last glimmer in the 16-day window, with a 6ft ENE swell and a clean offshore wind, but the period is short again.
So, to boil it down: the absolute standout is the morning of Wednesday the 26th of August. Massive, clean, powerful swell. For the slightly less crazy, Tuesday and Thursday mornings in that same week are also excellent. The rest is a bit of a mixed bag, with a long quiet stretch in the middle. Get on it while it's hot.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
